I've looked around and haven't seen this mentioned specifically. What brand/size 18 inch r-compound tires are you guys running for the track? I'm getting some Apex EC-7s (9.5 front, 10.5 rear)

and need some rubber for them.
Ideally, looking to go 265/35 front and 285/35 rear but don't think the rear exists in that size for any r compounds. For those of you running 295/30 in the rear, does the large size differential between front and rear (5% smaller in the rear) affect the abs/dtc systems?
What brands do you guys recommend?
Cheers
